Partial model to include a conditional HeatPort in order to describe the power loss via a thermal network
This partial model provides a conditional heating port for the connection to a thermal network.
If this model is used, the loss power has to be provided by an equation in the model which inherits from ConditionalHeatingPort model (lossPower = ...). As device temperature T_heatPort can be used to describe the influence of the device temperature on the model behaviour.
